More Information
Summary:An apparatus for reducing a radiation power and an electric field includes a transmission end energy transfer unit configured to include a feeding roof and a transmission coil, a receiving end energy transfer unit configured to be symmetrically separated from the transmission end energy transfer unit at a predetermined distance, and to include a receiving roof and a receiving coil, a first electric field shield configured to be made of a nonconductor, to have a shape surrounding the transmission end energy transfer unit, and to have an empty space of a predetermined first thickness; and a second electric field shield to be made of a nonconductor, to have a shape surrounding the receiving end energy transfer unit, and to have an empty space of a predetermined second thickness, wherein the empty spaces are filled with a dielectric material for shielding the electric field.
